Changing the name processor is just for fun ,and will not improove your sistem speed!
Ok to start all u have to do is copy the text from below:
Windows Registry Editor Version 5.00
"ProcessorNameString"="Intel Core i7 Extreme 965 Overclocked bY CrYs18 to 14.99 GHz"
Paste it to notepad ,modify the name of the processor as u like, go to Save as on notepad, name the file whatever u like like (Example: "trick.reg" ) remember to put extension ".reg", Save as type select "All files" , OK
No double click the file u created (egg. "trick.reg"), click Yes, then OK. Now u are done, go to Properties on My Computer and u will see the result!
